Model PT4109SFC USMC Carbon Dive
Description
The ProTek Model PT4109SFC USMC Carbon Dive is a purpose-built 45mm dive watch designed for those who demand reliable timekeeping in the most demanding environments. Built around a lightweight carbon composite case and a 316L stainless steel screw-in caseback, this watch pairs rugged construction with precision engineering. The 60-click unidirectional ratcheting bezel and 300-meter water resistance make it a true dive-ready instrument, while sapphire crystal with antireflective coating keeps the dial clear and readable under any lighting conditions.
Powering the watch is the dependable Japanese Miyota 2035 quartz 3-hand movement with a 4-year battery life, ensuring low-maintenance reliability for everyday wear and underwater use. The Swiss self-powered Pro-Glo T100 tritium illumination system delivers a continuous glow for 25 years without ever needing to be charged by an external light source - shining 100x brighter than conventional photoluminescent lume systems. Whether you're on a dive, a mission, or simply looking for a serious daily-wear timepiece, the PT4109SFC delivers performance you can depend on.

FAQ
What makes the Pro-Glo T100 tritium illumination different from regular lume?
The Swiss Pro-Glo T100 tritium system is self-powered by a natural radioactive process, meaning it glows continuously for 25 years without ever needing to absorb light from an external source. In contrast, standard photoluminescent lume must be "charged" by exposure to light before it glows - and that glow fades quickly. The T100 system is also rated to shine 100x brighter than conventional lume, making it far superior for low-light and underwater visibility.
Is the PT4109SFC suitable for scuba diving?
Yes. With 300-meter water resistance, a screw-in crown with multiple O-rings, and a 60-click unidirectional ratcheting dive timing bezel, the PT4109SFC is built to meet the demands of recreational and professional diving. ProTek tests every watch in both air and water before it ships, giving you added confidence in its depth rating.
What is the difference between the PT4109SFC, PT4101SF, and PT4105SFC models?
All three models share the same USMC Carbon Dive platform and core specifications. Differences between the models typically relate to dial color, bezel design, or strap configuration. If you'd like help choosing the right variant for your needs, feel free to reach out to us at service@omahasportsandgames.com.
How often does the battery need to be replaced?
The Miyota 2035 quartz movement is rated for a 4-year battery life under normal use. When the time comes, any watchmaker or jeweler with standard quartz battery replacement experience can service it quickly and affordably.
Can I swap the rubber strap for a different band?
Yes. The watch features a standard 22mm lug width, which means it is compatible with any aftermarket 22mm watch strap or bracelet. The included rubber strap is reinforced with a steel tube for added durability, but swapping to NATO, leather, or metal bracelets is straightforward with standard spring bar tools.
